Seems to work for the few vids I've tried....C"YouTube has been testing higher bitrate encodings of it videos, which you can see if you add a &fmt=8 or &fmt=16 to the video url. Historically, all videos have been delivered to the lowest common denominator: sorenson encoded 320x240. By adding &fmt=6 to the URL, the video is served up in 448x336 resolution and I'm guessing it's using the VP6 codec (can anyone confirm?). &fmt=18 gives you the iPhone-style MP4 stream" [snip]
